Summary: Finds OpenMP directives that are allowed to contain `default` clause, but either don't specify it, or the clause is specified but with the kind other than `none`, and suggests to use `default(none)` clause. Using `default(none)` clause changes the default variable visibility from being implicitly determined, and thus forces developer to be explicit about the desired data scoping for each variable.
